Dr. Edmund Kraiselburd, Director, Caribbean Primate Research Centre: "The longevity of this programme is mainly behavioural research. In the island there is no vaccine developing studies or anything like that. You will find mainly people who are studying sociobiology, the study of how monkeys interact with themselves - What is fear? How do you choose your mate? How you exert power on others? And so, essentially monkeys, in a way, they are a reflection on us, what we are, why we behave this way. So people are using monkeys as a model to understand humans, in a way. So understanding monkeys, we understand ourselves." .
